L’extension GeoData permet aux articles de fournir leurs coordonnées géographiques et de les publier via l’API HTTP.
Installation
Moteurs de recherche
D'abord il faut décider du moteur à utiliser pour la recherche :
- MySQL (par défaut) : est adapté pour les installations de petites et moyennes dimensions. Ne nécessite pas de configuration. Il n’utilise pas les index spatiaux intégrés de MySQL parce que quand l’extension a été développée, SPATIAL n’était pris en charge que par le moteur de stockage MyISAM, qui est pire que rien du tout. Au lieu de cela, il utilise des tuiles de 0,1 × 0,1 degrés pour les recherches, ce qui produit des entrées/sorties un peu plus élevées, mais des mises à jour plus rapides.
- ElasticSearch est un moteur de recherche puissant. Lors de l’utilisation d’ElasticSearch en tant que moteur, GeoData fonctionne comme un greffon pour CirrusSearch qui ajoute la recherche de texte ES au wiki.
Processus
- Téléchargez et placez le(s) fichier(s) dans un répertoire appelé
GeoData
dans votre dossierextensions/
.
Les développeurs et les contributeurs au code doivent à la place installer l'extension à partir de Git en utilisant:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/GeoData - Ajoutez le code suivant à la fin de votre fichier LocalSettings.php :
wfLoadExtension( 'GeoData' );
- Exécutez le script de mise à jour qui va créer automatiquement les tables de base de données dont cette extension a besoin.
- If you're about to use GeoData with ElasticSearch, install CirrusSearch then add to LocalSettings.php, below the GeoData loading.
$wgGeoDataBackend = 'elastic';
- Fait – Accédez à Special:Version sur votre wiki pour vérifier que l'extension a bien été installée.
Utilisation
This extension adds a new parser function , {{#coordinates:}}
, that saves coordinates to the database. Function's input format is made as compatible as possible with GeoHack.
Glossaire
- Coordinates - see w:geographical coordinates
- Globe - terrestrial body on which the coordinate resides. By default, Earth is assumed. Internally, globe is represented as lowercase strings. The following globes are supported:
earth
,mercury
,venus
,moon
,mars
,phobos
,deimos
,ganymede
,callisto
,io
,europa
,mimas
,enceladus
,tethys
,dione
,rhea
,titan
,hyperion
,iapetus
,phoebe
,miranda
,ariel
,umbriel
,titania
,oberon
,triton
andpluto
. Globes not mentioned in this list will be assumed to have generic characteristics: longitude range 0-360°, Eastern longitude is positive. Longitude sign for known globes is taken according to IAU's conventions. - dim - approximate size of an object. Used by GeoData to restrict search and by GeoHack for determining appropriate map zoom. The default unit of measurement is metres, although the km suffix may be appended to indicate kilometres.
- Primary vs. secondary coordinates: primary coordinates define article subject's location, while secondary coordinates are other coordinates mentioned in the article. There can be only one primary coordinate per article, but as many secondaries as you like barring technical restrictions.

) are always ignored.- latitude and longitude can be specified in several formats:
- Direct signed input in degrees, e.g.
37.786971|-122.399677
, which corresponds to 37° 47′ 13.1″ N, 122° 23′ 58.84″ W.- As formatted number in the content language. Use
{{formatnum:}}
, to format a number of a expression.
- As formatted number in the content language. Use
- Degrees/minutes or degrees/minutes/seconds, e.g.
37|47.2183|-122|23.9807
or37|47|13.1|-122|23|58.84
. - Either of the above, but with sign specified by N/E/S/W letters:
37.786971|N|122.399677|W
37|47.2183|N|122|23.9807|W
37|47|13.1|N|-122|23|58.84|W
- Direct signed input in degrees, e.g.
- primary keyword specifies that these coordinates are primary (see #Glossary).
- Extra parameters are any combination of the following named parameters:
- dim: approximate size of the object.
- scale: Scale of map display for this object, e.g. scale of 300 is 1:300. Gets converted into dim internally using formula dim = scale / 10. If both scale and dim are set, dim has precedence.
- globe, see #Glossary.
- name: name of this point, up to 255 bytes (UTF-8).
- region: ISO 3166-1 alpha-2 country code (e.g. US or RU) or an ISO 3166-2 region code (e.g. US-FL or RU-MOS). This parameter is always capitalised internally.
- type: type of object with these coordinates, can be one of the following: country, satellite, state, adm1st, adm2nd, adm3rd, city, isle, mountain, river, waterbody, event, forest, glacier, airport, railwaystation, edu, pass, camera, landmark.
type | Description | Dim |
---|---|---|
country | (e.g. "type:country") | 1,000,000 |
satellite | geo-stationary satellites | 1,000,000 |
adm1st | Administrative unit of country, 1st level (province, state), e.g. U.S. states | 1,000,000 |
adm2nd | Administrative unit of country, 2nd level, e.g. US county | 30,000 |
adm3rd | Administrative unit of country, 3rd level | 10,000 |
city(pop) | cities, towns, villages, hamlets, suburbs, subdivisions, neighborhoods, and other human settlements (including unincorporated and/or abandoned ones) with known population (optional population in braces is ignored) |
10,000 |
airport | airports and airbases | 3,000 |
mountain | peaks, mountain ranges, hills, submerged reefs, and seamounts | 10,000 |
isle | islands and isles | 10,000 |
waterbody | bays, fjords, lakes, reservoirs, ponds, lochs, loughs, meres, lagoons, estuaries, inland seas, and waterfalls | 10,000 |
forest | forests and woodlands | 5,000 |
river | rivers, canals, creeks, brooks, and streams, including intermittent ones | 10,000 |
glacier | glaciers and icecaps | 5,000 |
event | one-time or regular events and incidents that occurred at a specific location, including battles, earthquakes, festivals, and shipwrecks | 5,000 |
edu | schools, colleges, and universities | 1,000 |
pass | mountain passes | 1,000 |
railwaystation | stations, stops, and maintenance areas of railways and trains, including railroad, metro, rapid transit, underground, subway, elevated railway, etc. | 1,000 |
landmark | buildings (including churches, factories, museums, theatres, and power plants but excluding schools and railway stations), caves, cemeteries, cultural landmarks, geologic faults, headlands, intersections, mines, ranches, roads, structures (including antennas, bridges, castles, dams, lighthouses, monuments, and stadiums), tourist attractions, valleys, and other points of interest | 1,000 |
Default dim: if no type is used or the type is unknown to this extension | 1,000 |
- GeoHack parameters: one or more pairs in format parameter:value, delimited by underscores (_) or spaces (e.g.
dim:1000_type:city
). No spaces are allowed between parameter and colon or between colon and value. The parameters are the same as extra parameters above. If a parameter exists in both GeoHack parameters and extra parameters, extra parameters always have precedence. This input is needed only for compatibility with preexisting {{coord}} templates - if your wiki is only designing a geographical coordinates template, it is best if you not used raw GeoHack parameters at all.
Exemples
Note how extra parameters are specified:
{{#coordinates:primary|40.775114|-73.968802|type:landmark_region:US-NY|name=Loeb Central Park Boathouse}}
Inclusion dans les modèles
Conditions d’erreur
GeoData checks the data it receives for a number of error conditions.
The following conditions result in coordinates being outright rejected and added to tracking category (the name of it is defined by MediaWiki:Geodata-broken-tags-category):
- Coordinates out of range:
{{#coordinates:56|04|N|190|00|E}} {{#coordinates:76|61|03|N|37|25|30|W}}
- Mixing coordinate signs and hemisphere letters:
{{#coordinates:primary|-26|04|N|178|46|E}} {{#coordinates:primary|26.16|N|-178.76|E}}
- More than one primary coordinate on page:
{{#coordinates:primary|26|04|N|178|46|E}}{{#coordinates:primary|26|04|N|178|46|E}}
- Too many coordinates on page: by default 500, 2000 on WMF.
The following errors are non-fatal by default:
- Unrecognised coordinate type:
{{#coordinates:primary|26|04|N|178|46|E|type=New York}} {{#coordinates:primary|26|04|N|178|46|E|type:village}}
API
GeoData has two API modules that perform search around a given point and coordinates for a given article(s).
list=geosearch
Searches for articles around the given point (determined either by coordinates, bounding box, or by article name).
Parameters:
- gscoord
- Coordinate around which to search: two floating-point values separated by pipe (|)
- gsradius
- Search radius in meters (10-10000). This parameter is required with the use of gscoord.
- gsbbox
- Bounding box to search in: pipe (|) separated coordinates of the corners in top|left|bottom|right order.
- gspage
- Title of page around which to search
- gsmaxdim
- Restrict search to objects no larger than this, in meters
- gslimit
- Maximum number of pages to return. No more than 500 (5000 for bots) allowed. Default: 10.
- gsglobe
- Globe to search on (by default
earth
). - gsnamespace
- Namespace(s) to search. Default: main namespace.
- gsprop
- What additional coordinate properties to return. Values (separate with '|'): type, name, country, region.
- gsprimary
- Whether to return only primary coordinates (
primary
), secondary (secondary
) or both (all
). Default:primary
.
Example:
- Search around the point with coordinates 37° 47′ 13.1″ N, 122° 23′ 58.84″ W:

Enumérer les pages avec ou sans les coordonnées
GeoData extends two core API modules, list=allpages
and list=categorymembers
. The extended modules are called geopages
and geopagesincategory
. It adds two mutually exclusive parameters, withcoordinates
and withoutcoordinates
.
Configuration
Paramètres | Type | Valeur par défaut | Action |
---|---|---|---|
$wgMaxGeoSearchRadius |
int | 10000 | Maximum radius for geospatial searches, in meters. Reducing this value reduces server load |
$wgMaxCoordinatesPerPage |
int | 500 | Maximum number of coordinates per page, -1 means no limit |
$wgTypeToDim |
array | Long array, see the sources | Conversion table type --> dim |
$wgDefaultDim |
array | 1000 | Default value of dim if it is unknown |
$wgGlobes |
array | Long array, see the sources | Defines parameters of every globe |
$wgGeoDataWarningLevel |
array | array(
'unknown type' => 'none',
'unknown globe' => 'none',
'invalid region' => 'none',
)
|
Controls what GeoData should do when it encounters some problem. Reaction type:
|
$wgGeoDataIndexGranularity |
int | 10 | How many integer units per degree to use with database-only search. Influences performance. Run updateIndexGranularity.php after changing this setting. |
$wgGeoDataBackend |
string | 'db' | Which backend should be used by spatial searches: 'db' or 'elastic'. Note if you're planning to change it, do so before creating the database tables. |
